I've been meaning to build a resistance solder unit. I went to the
local RS yesterday to see what types of transformers they had. They
didn't have anything close to what I hoped to find. Not deterred I
went to an electronics store. There sure were a number of large flat
screen tvs in for repair! I gave the tech what I hoped would be an
easy part to provide. Nope, he said, try Jameco on line. So I came
home and I did. Either I'm not sure what to put in the filter or I'm
looking for an oddity.
I'm trying to build a resistance solder unit.
I've searched on-line.
For the curious here are a couple of links:
http://www.girr.org/girr/tips/tips1/solderer.pdfBut this one uses a battery charger. I was hoping for something a bit
smaller and more home-brew.
This is more like what I was hoping to find but a bit pricey:
http://www.istnet.net.au/~wamrc/res_solder/index.htmlYeah, I also went out to the Train Index. I have the Mainline Modeler
magazine. That's what started this train of thought.
And there is this reference too:
http://www.trainweb.org/bristol-s-gauge/Projects/rsu.htmlSo what the heck am I looking for???
I thought I knew!
One article suggests a transformer that takes house current and on the
secondary posts gives 6-8 volts AC at 3 Amps. That's what I was asking
for at the local stores.
Another articles says I need a filament transformer that provides less
than 7 volts at 6 or more AMPS.
So far no luck. Any help appreciated.
